Scale:
0: If you're bigger and scarier some people might buy it. If you're smaller and not scarier they might humor the lunatic screaming at them.
1: You have a glare. It's a pretty good glare!
2: Your glowering is A+.
3: Your ability to convey potential, impending violence could now be taught at the college level.
4: Everyone is scared of you but never seems to notice that you don't actually need to hurt people.
5: It honestly doesn't matter how dangerous you really are, everyone just takes you seriously.
6: Even when they are far, far, far scarier.
